Log splitter

ABSTRACT

An upright free-standing log splitter operated by a vertical ram energized from any source desired such as a tractor to which the log splitter may be secured, or a trailer. The log splitter may be placed on a rear part of a truck or the like by means of parallel bars so that the splitter may be placed on the ground or raised for transportation. Wheels may be provided for the working platform or bed of the splitter so that it may be trailered.

BACKGROUND OF THE INVENTION

There have been many log splitters suggested most of which provide awedge type ax head and can be used to split relatively small logs onlyas for instance in a horizontal position, and it is the purpose of thepresent invention to provide a log splitter having a much greatercapacity and which is very easily controlled and transported.

SUMMARY OF THE INVENTION

The present log splitter comprises a base or platform upon which thewood stump or section of log is to be placed while being split. A pairof relatively widely spaced channel irons facing each other are fixed inupright position on the base and these guide between them the splitterblade which comprises an elongated blade stretching between the twochannel irons and backed up by relatively large triangular platessecured thereto, vertical sides of the triangular plates being receivedin the channels thereby stabilizing the blade in spite of its greatlength so that it will not bind in the channels regardless of pressuresexerted.

An attachment is provided for mounting one of said channels onto atractor so that the hydraulic system of the tractor can be used to powerthe splitter, but also one channel may be secured with respect to anupright member on a trailer which may have its own motorized pump forthe purpose of operating the splitter. Also the basic unit may bemounted on swingable parallel bars as for instance on the rear of atruck and may be self-energized for lifting to and from the ground; thebase being on the ground for operation and then lifted up onto the sideof the truck for transportation.

PREFERRED EMBODIMENT OF THE INVENTION

The base of the splitter is a heavy built up box-like square basegenerally indicated at 10. This base is reenforced by various braces 12extending across the same. At each side of the base opposite each otherare a pair of channel irons 14, 16, the channels of these irons facingeach other forming guideways for the blade assembly. The blade isindicated generally at 18 and extends across between the two channelsthe distance of e.g., in this case about 31 inches, almost 30 inches ofwhich is available for splitting. It can be seen that a large section oflog can be serviced having a diameter much greater than the openingbetween the channels 14, 16, because it can be split at the edge andthen be turned for further splitting. The blade actually splits sliceswhich are turned for group splitting into billets.

The blade is provided with a bracket 20 by which it is secured to thelower end of a piston rod or ram 22 of a hydraulic cylinder 24.

At each end of the blade 18 there are provided massive triangular guidewings 26 and 28 each of which has an elongated edge 30, secured in achannel 32, see FIG. 6, which slidingly fit and ride in the channels 14and 16. These wings prevent any kind of wobble or tendency to bindbecause of the length of the wings which are e.g. 2 feet in length. Anyextraneous force at any point inwardly on one guide is transferredthrough the blade, which is itself of massive dimensions, to the otherwing, equalizing any tendency to bind due to a tendency to cock if suchshould occur.

Piston 24 is mounted on a double angle iron or the like 34 mounted inany way desired at its ends as at 36, 38 to the upright channel irons infixed position relative thereto. Conventional hoses and controls, seecontrol box 40, are conveniently mounted on the channel iron 14. On thechannel iron 16 there is mounted another shorter channel iron 42 facingin the opposite direction and providing bolted-on supports for mountingthe entire splitter directly on any kind of trailer or through a fixtureor bracket generally indicated at 44 onto a tractor not shown ofconventional design.

This bracket comprises a horizontal member 46 from which extend atangles thereto a pair of wings 48 and 50 at the lower ends of which isan iron cross bar 52 having pins 54 and 56 at the ends thereof forconnection to linkages 58 and 60 of the tractor. The tractor has alinkage 62 whereby the device is held firmly into position as shown inFIG. 1. The bracket 44 is not needed with a trailer. The unit shown inFIG. 1 may be used without the bracket, with the base 10 merely set onthe ground and operated by the hydraulic system of any vehicle orseparate engine.

Also wheels may be applied to the base 10 for trailering operations andthese wheels are easily removed to set the base 10 on the ground foroperation.

Referring now to FIG. 3 there is here shown e.g., the rear panel 63 of adump truck on one side of which there is mounted an upright spindle orthe like 65 having brackets 66, 67 pivotally mounted parallel bars 68and 70 which are pivoted with respect to the channel iron 42, and thesplitter as shown in FIG. 3 is exactly the same as the one shown in FIG.1 but without the bracket 44.

As shown in FIG. 4 the parallel bars can be used to swing the entiresplitter down onto the ground or it can be easily raised and held inposition by a link 72 for transportation purposes being latched down byany desired means. It will be noted that the spindle 65 is outboard ofthe truck body at the corner of the back and side thereof, and thismeans that the entire parallelogram with splitter attached can be swungaround 270° and can be used anywhere on the ground in that arc. Also thedump truck panel can be lowered and the truck dumped with the entireapparatus swing 180° to 270° away from the position shown in FIG. 3,completely out of the way of the panel 63.

The blade is massive as shown in FIG. 5 and comprises a bar hollowground at 73, 73 forming a wide splitting wedge. The striking edge 74 isflat-sided but also forms a wide wedge for the best splitting action.

The characteristics of this log splitter are very simple but rugged andit has an enormous and very fast capacity for its intended purpose.

The blade has a pair of apertures 78, 78 therein for the reception ofpins 80, 80, extending rearwardly from the rear of truck or othervehicle shown in rear view in FIG. 4. Pins 80, 80 may be on any part ofthe vehicle or on a plate 81 or the like. With base 10 on the groundbehind the vehicle, the blade is raised to align the apertures 78 withpins 80, and the latter are thrust into the apertures. The ram haspressure applied to it, and the blade being now fixed, the base risesand can be locked in any way to hold it above ground, FIG. 3, fortransportation.

Trailer wheels 82, 82 on a frame 84 are used similarly. Plates 86, 86fixed to frame 84 are fastened to blade 18 by pins 88, 88 taken intoapertures 78, 78, with the frame 84 straddling the base 10. With thebase on the ground, pressure is applied to the ram, and the base risesoff the ground, FIGS. 7 and 8, to trailering position.

I claim:
 1. A log splitter comprising a base, a pair of spaced standards thereon, each standard being located at an opposite edge of the base, a support joining the standards at a point spaced from the base, a sharpened splitting blade, said blade extending between the standards at the side of the support toward the base, the base, blade, and support all being parallel,a hydraulic cylinder on the support, a piston rod for the cylinder, means to supply fluid pressure to the cylinder to relatively extend said rod and said cylinder, means connecting the rod to the blade, means slidingly guiding the blade at its ends, said means including wings on the blade, said wings extending from the blade toward the support, and means on the wings sliding engaging the standards, including a wheeled frame, means to connect the blade to the frame with the blade spaced above the base, whereby pressure in the cylinder will raise the base relative to the frame.
 2. The log splitter of claim 1 wherein the wheeled frame is a trailer.
 3. The log splitter of claim 1 wherein the wheeled frame is a part of a vehicle.
